After a slew of bad headlines hit his companies, billionaire entrepreneur Elon Musk ripped into the press in a Twitter rant on Wednesday that culminated with a suggestion for ranking media credibility, and drew inevitable comparisons to President Donald Trump’s attacks on “fake news.”

“The holier-than-thou hypocrisy of big media companies who lay claim to the truth, but publish only enough to sugarcoat the lie, is why the public no longer respects them,” Musk wrote in response to a Robert W. Baird & Co. analysis that claimed “increasingly immaterial” headlines have dominated Tesla’s news cycle.

Some of Musk’s 21.8 million followers accused him of “trolling” the media, but the mogul hit back at accusations that he was like Trump.

“Anytime anyone criticizes the media, the media shrieks ‘You’re just like Trump!’” he tweeted.

At which point Donald Trump Jr. weighed in. “This…So true!!!” he tweeted.

Musk’s Twitter diatribe comes after Consumer Reports found “flaws—big flaws” with Tesla’s Model 3, including serious issues with the brakes. The Center for Investigative Reporting’s Reveal website also published an article last month saying Tesla factory management deliberately failed to report injuries in order to make its numbers look good. A statement Tesla sent to Reveal called the story “a calculated disinformation campaign.”

“They’re just some rich kids in Berkeley who took their political science prof too seriously,” Musk tweeted.

He threatened to create a site where the public could assign articles, journalists, editors and publications a “credibility score”, and even opened a poll on whether he should pursue the idea.

“Thinking of calling it Pravda,” he wrote, referring to the Russian word for truth and formerly the official newspaper of the Communist Party of the Soviet Union.
